SPECIFICATION forming part of Letters Patent No. 532,201, dated January8, 1895.

' Application filed May 31,1894. Serial No. 513,032- (No model.)

To all whom it may concern.-

Be it known that I, ELIAS HINES, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, have.invented certain new and useful Improvements in Doors; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in doors and of that class ofdoors which are ordinarily used at all outside entrances to public orother buildings and known as storm doors.

The object of the invention is to provide a door of an entirely newconstruction and so made and hung as to be swung with very littleefiort, and furthermore, the object is to provide a door which will notand cannot be opened by wind or by strong drafts passing through thebuildings.

Ordinarily doors for public buildings are heavy and cumbersome andrequire a very great eifort to open them for the reason that strongsprings must be used so that the wind cannot open them.

In the drawings presented herewith, Figure 1 represents a perspectiveview of the door showing the mode of hanging same. Fig. 2 is a plan viewof the door showing. its position in the doorway and direction in whichit swings. Fig. 3 is a plan view of a modified form of door embodyingthe same features above described.

A represents the door as placed within the opening in the casing B. Thisdevice is composed of two wings O and D which are joined together toform a single rigid door. The two wings C and D overlap at theiradjoining portions and form the shoulders G and H. At the top and bottomof the door thus formed, pins E and F respectively are insertedvertically. These pins form pivots for the door to swing upon; the pin Ebeing sooketed in the top of the casing B and the pin F in the fioor. Acoil spring E surrounds the pin E, one end being suitably attached tothe door and the other end to the casing. A similar spring F may also beplaced on the lower pin F if desired.

A stop I may be fastened to the casing or to the floor to limit theswing of the door when seeking its normal or closed position.

The upper half of the wings O and D may be supplied with glass ifdesired and the lower portion with paneling as in other doors. The doormay also be made with an entirely plane surface as shown in Fig. 3, 2'.6., with no offset as has been described, as it is not absolutelyessential.

The advantages of this door is the ease with which it is made to swingon its pivots. The weight of the door being evenly distributed on eitherside of the pivots, it is very evident that the force or pressurerequired to swing the door will be quite small, and for the same reason,the spiral spring need not be of great'strength. When a person entersthe door he takes the right hand side. This he will naturally do, as theright hand wing on either side is set back from .the left side.

Two persons passing in opposite directions V serious injuries on personswho were too slight I to manage them.

In view of this, then, the door described herein has anotheradvantage-the door being mounted on the central pivots as it is, a gustof wind striking it has no effect since it must strike the entiresurface of the door. Thus the pressure on one side is neutralized by thepressure on the other side.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, in a door, of the two wing sections 0 and D overlappingand joined at their adjacent edges whereby each of said sections isparallel with but out of line with its neighbor for the purposes setforth, pivots E and F mounted in the top and bottom of the door at thejuncture of the said wing seotions, and the spring E surrounding one ofthe said pivots substantially as set forth and described. 7

In testimony whereof I afiix my signature in presence of two witnesses.

ELIAS HINES.
